The objective of this article is to introduce a new digital technology that can be used to address this challenge showing its advantages and limitations. First Fit is a digitally guided tooth preparation system that can be used to control the accurate and efficient preparation of teeth. In some cases, the system can be used to prepare the teeth for previously made restorations based on planned digital reduction.  \nClinical considerations: The First Fit system uses 3D-printed guides and a specially designed handpiece for guided veneer preparation using either a one-step or a twostep approach. In the one-step approach, final restorations are produced prior to preparation of the teeth using reduction guides, and veneers are cemented on the same day as preparation. The two-step approach includes a preparation phase during which the teeth are prepared using a combination of the reduction guides and freehand techniques. Cementation is then completed at a second appointment. Conclusion: The First Fit system controls and guides veneer preparation with a minimally invasive approach. In some cases, it enables the production of veneers before tooth preparation, alleviating the need for provisional restorations.  \nClinical significance: The guided restorative dentistry technique described here utilizes digital CAD-CAM technology to achieve predictable and accurate results in a minimally invasive and efficient manner.  \nKEYWOR DS  \nCAD-CAM, digital dentistry, digital smile design, guided dentistry, veneers  \n1 | INTRODUCTION  \nCeramic veneers have been a successful treatment modality since the 1980s. Since their introduction, different techniques for preparation have been proposed to create adequate space for the restorative material. In terms of long-term outcomes, ceramic veneers have been correlated with enamel preservation. The literature shows that the presence or absence of enamel is critical and, as a result, conservative veneer preparation is essential.1-7  \nCoachman et al proposed a three-generation classification to describe veneer preparation techniques. The first generation refers to  \npreparations exclusively guided by calibrated burs to standardize facial and incisal edge reduction.8 This reduction is driven in part by the existing surface of the tooth and aims to reduce the tooth structure ina uniform way. However, in some instances, this approach can result in aggressive preparations as the technique does not take into account, among other things, the position and anatomy of the final restoration or wear and loss of existing enamel. Consequently, thereis high risk of dentin exposure.9  \nThe second generation refers to Magne's use of a diagnostic waxup as a blueprint. In this technique, silicone indices are made over the wax-up to guide incisal and facial reduction.10 This approach aims to  \nJ Esthet Restor Dent. 2020;1–11.  \n[wileyonlinelibrary.com/journal/jerd](wileyonlinelibrary.com/journal/jerd)  \n© 2020 Wiley Periodicals, Inc.  \n1  \ncreate the necessary space by taking into account the proposed restorative material and the future anatomy of the restoration.
